I don't think these are really stone arrows, and force sounds like the closest thing to an "arrowlike magical attack" (unless we want some other kind of energy damage). I'd also say make this a regular ranged attack (as opposed to touch) unless we want to say the force burns through armor. Max range of 360 ft, no range increments? Or make it have a range increment like a bow?The bow is not a true bow, and the arrows are stone, but they allow the archer to make an arrowlike magical attack which hits with a THAC0 of 17 and inflicts 1d10 points of damage. The "arrow" has a range of 120 yards.
I'd say give it a slow climb speed since it doesn't seem to have a fly speed like the normal gargoyle.
